Hey Gauge - hold off doing anyhting for now there's a Hempy grower called ash-a-ton who's doing a grow (looks like it's rocking!)
https://www.autoflower.org/threads/ash-a-ton-and-the-hybrid-hempy-bucket.59754/page-18#post-1536537
I've asked to see if he can take a look and maybe offer some advice (or at least put me straight lol)
Hopefully he'll pop in and be able to better advise!
For lowering the PH, i'd always adjust the PH after putting the feed in (as A&B will adjust the ph after being put it)
If it's chemical feeds (which it is) you can use Nitric acid in Veg and some would say Phosphoric acid in flower (however, you can adjust it with either/or all the way through)
In a pinch you could use lemon juice as PH down - although it wont hold such a stable PH.
I doubt you'll ever need PH up ... if i ever go to far with the PH down ,, unless it's a tiny bit that rhizotonic could bring up, i'd scrap the feed and start again (frustrating .. but teaches a lesson in being careful with the acid lol)
Use a digital PH reader for testing. A cheap one is called "essentials" and they're good eanough. a really nice one is called bluelabs ... but they're pricey!
Hope this helps
